Evaluation of Web API Performance Efficiency Using Object Relational Mapping in Point Of Sale Applications Using ISO 25010

Abstract

The Point of Sale application is an application that handles a sales transaction activity and a product purchase. In this study, the Android-based Point of Sale application was developed using the Object Relational Mapping approach to overcome (impedance mismatch) and increase productivity, performance and system maintenance. So that the application of the Object Relational Mapping approach needs to be evaluated to measure the quality of a system. ISO/IEC 25010 is one of the international system measurement standards which has 6 measurement characteristics, one of which is the measurement of the Performance Efficiency of a system. Performance Efficiency has 3 sub-characteristics namely Time Behaviour, Resource Utilization, and Capacity. Web API Point Of Sale that implements the Object Relational Mapping (ORM) approach has met better Performance Efficiency standards compared to Web API that does not use the Object Relational Mapping approach with an average response time difference of 14.8 milliseconds when tested per 1 user. And has a faster average response time and higher throughput when tested with many users simultaneously.
